I just tried an amazon warehouse deal on one of these - i couldn't detect ANY fan whatosever. There is i believe a fan on the PG32UQX and on the 27" variants. I am not saying there isn't a fan, but if there is i couldn't detect it. Only reason monitor is going back is it was cutting out / not waking up after 24 hours of use (guess thats why someone else setn it back before me). I am super tempted to buy one new given my experience - not perfect, but great value IMO compared to the PG32UQX.
